There’s no one definitive answer to this question, as there are many different types of trolls in Skyrim. However, some of the more common ones you’ll likely find include the trolls that live in the swamps and forests near the river delta, as well as those that live in the hills and mountains. If you’re looking for troll fat, it’s best to start by looking for them near water sources. Trolling for food is a common practice among these creatures, so they’ll often be found near bodies of water where they can scavenge food from animals or humans. If you’re lucky enough to find troll fat on your own, be sure to cook it over a fire before eating it. Troll fat is very filling and will help you feel full after eating small amounts.
